以 LED 为光源的手术无影灯比传统卤素无影灯有无可比拟的优点,而光斑尺寸可变又是无影灯的一个重要指标。但此时可变光斑的光学分析比较困难,为此用改型的高斯函数构建了单模块光斑及总光斑照度分布的数学模型,从而找出无影灯的照度分布在符合行业标准的范围内随单光斑形状、移动量等参数而变的规律。由模拟计算的结果可以确定无影灯总体光学设计中的重要参数,并提供 LED 透镜设计的要求。
以 LED 為光源的手術無影燈比傳統滷素無影燈有無可比擬的優點,而光斑呎吋可變又是無影燈的一箇重要指標。但此時可變光斑的光學分析比較睏難,為此用改型的高斯函數構建瞭單模塊光斑及總光斑照度分佈的數學模型,從而找齣無影燈的照度分佈在符閤行業標準的範圍內隨單光斑形狀、移動量等參數而變的規律。由模擬計算的結果可以確定無影燈總體光學設計中的重要參數,併提供 LED 透鏡設計的要求。

In contrast to traditional metal halide surgical luminaries , the LED surgical luminaries have unmatched advantages.The variation of the lighting diameter is the important mark for surgical luminaries . But the optical analysis of variable lighting spot became difficult due to this .A modified Gaussian function was used in this paper to construct the illuminance distribution of single module light spot and total light spot.The variation rule of the illuminance distribution following the change of the shape and the shift amount of single light spot can be found within the range specified by the industrial standard .The important parameters in the overall optical design can be determined , and the requirement for the LED lens design is provided.
